信息安全在信息社会扮演着越来越重要的作用,研究密码学是保障信息安全的重要课题。本论文提出了一个基于压缩态非高斯调制的四进制量子密钥分配协议,通过对误码率的描述,分析了协议在Eve采用最佳攻击一纠缠克隆攻击时的安全性。
Information security plays an increasingly important role in the information society. Studying cryptography is an important issue for information security. In this paper, a quaternary quantum key distribution protocol based on compressed non-Gaussian modulation is proposed. By describing the bit error rate, the security of the protocol when Eve is attacked by the best attack-entangled clone attack is analyzed.
